Primefaces extension keyfilter doesn't allow to paste values

Question

I'm using keyfilter from Primefaces extensions library, <pe:keyfilter/>. I use it together with regular expression which permits only numbers to be input. Everything works fine except that I can't paste a value into a field even if it fulfills regex. I mean I can't perform ctrl+v or right click -> paste with the mouse.

Is there workaround of this issue?

Or should I just use another validation method?

Check out documentation. It has an attribute preventPaste, you should try set it to false.

This is the PrimeFaces keyfilter, not the PrimeFaces extensions keyfilter! – Kukeltje Jun 02 '17 at 10:18
It helped me I had primefaces key filter. The most idiotic default setting I've ever seen – hocikto Dec 19 '18 at 15:06
Thanks for the hint! Also helps me. But with "prependPast="false", you can again past wrong characters. – Martin Metz Nov 25 '19 at 14:31

You could use <pe:inputNumber/> instead as a input field.

To get integer numbers you could just use <pe:inputNumber value="..." decimalPlaces="0"/>.
I just tested it and it worked with pasting numbers, but pasting text did also work. But when exiting the field, the wrong text input would then vanish. Not the best solution, but atleast you can paste numbers.
